2. Cladogenesis: similar derived species and unsimilar derived species

Question 2

Evolution types

Answer 2

Question 4

Type of Cladogenesis

Answer 4

1. Disruptive selection

2. Geographic isolation

Question 5

Paces of Speciation

Answer 5

Question 6

Allopatric speciation

Answer 6

Geographic isolation

Question 7

Sympatric speciation

Answer 7

Speciation in the same areas

*fruit flies w/ maltose and sucrose

Question 8

Ring species

Answer 8

Similar genetic traits from same parent but cannot interbreed

Question 9

Isolation Types

Answer 9

1. Prezygotic
   * Temporal
   * Spatial
   * Pollinators
   * Reproductive barriers
   * Chromosomes
2. Postzygotic
   * Non-viable offspring [hybrid necrosis]
   * Sterile offspring
